The wireless router I have now is fine, but I was thinking I'd like to
have a wireless router with external antennas so I can maybe fine-tune
the signal strength a bit (i.e. virtually NO signal going out the back
wall of my house and LOTS of signal going INTO my house.) Is that
something that's possible using a wireless router with external
antennas, even if I have to get replacment 3rd-party antennas for the
router?
